- the subject matter herein generally relates to the field of heat dissipation.
- a mobile terminal may include a main body and a speaker unit for providing audible information.
- An upper cover may have a display for displaying a text and other information.
- a lower cover may be coupled to the upper cover to cooperatively form a space in which various components can be mounted.
- a printed circuit board (PCB) may be installed in the space. In receiving/transmitting information or using its various functions (such as games or the like), a user may press the display with a finger to input information.
- the components of the printed circuit board inevitably generate heat due to collisions of electrons caused by operation of the component.
- the heat generally cannot evenly spread through out but concentrates on a specific portion thereby forming a hot area.
- the upper cover is usually the hottest part.
- life span and performance of components of the printed circuit board may deteriorate due to the heating over an extended period.

- FIG. 5 is an enlarged view of circled portion V of FIG. 3 .
- FIG. 6 is an enlarged view of a circled portion according to another embodiment of this disclosure.
- Coupled is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections.
- the connection can be such that the objects are permanently connected or releasably connected.
- outside refers to a region that is beyond the outermost confines of a physical object.
- inside indicates that at least a portion of a region is partially contained within a boundary formed by the object.
- substantially is defined to be essentially conforming to the particular dimension, shape, or other feature that the terms modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder.
- comprising when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
